Cosmograph Daytona Art.No.164136
JF’s blockbuster product. Rolex KV6 free‑sprung Daytona is here!
I. Case Craft (904L Stainless Steel)
• Material: 904L stainless steel identical to the original, corrosion‑resistant, scratch‑resistant and solid‑textured.
• Dimensions: 40 mm diameter, 11.9 mm thickness, fully consistent with the original.
• Finishing: High‑gloss polished case sides; natural transition between brushed and polished lugs and case body; precision CNC carving with sharp edges and no burrs.
• Lugs / End links: Independently moulded end‑links fit seamlessly to the case; top flush with case, rear slightly concave, bottom indented to match original structure.
• Case back: Fine brushing on steel versions; precious‑metal versions (rose gold / white gold) are engraved with 750 / St. Bernard dog head mark, clear and deep engraving. New 4131 case‑back features a wider flat surface for better wrist comfort.
• Crown / Shoulder guards: Three symmetrical shoulder guards. Crown logo matches the size at the 3‑o’clock position with curved profile. Screw‑in structure restores water‑resistance performance.
II. Ceramic Bezel (Original Core Advantage of C Factory)
• Material: High‑purity ceramic via nano‑sintering, high hardness, scratch‑proof and colour‑fast.
• Engraving: Deep laser engraving filled with platinum powder (not electroplated), grainy texture, no blackening or colour fading.
• Fonts: Three‑dimensional and rounded numerals / scales with slightly rounded edges, matching the original.
• Colour consistency: JF adopts original “Clean‑style bezel”. Industry‑leading colour matching for black / white / grey / rose‑gold bezels.
• Fit: Bezel fits tightly against case, no wobble or gaps.
III. Dial
• Panda Daytona: Exclusive true‑white dial, no yellowing or reddish tint, accurate colour tone.
• Printing: 3‑D pressure printing. Fonts such as “Rolex / Cosmograph” are sharp, no ghosting or offset.
• Sub‑dials: 3‑o’clock, 6‑o’clock and 9‑o’clock sub‑dials match original size and texture. Frosted sunburst / CD patterns are reproduced; clean borders without burrs.
• Hour markers: Inlaid three‑dimensional markers with rounded edge finishing, flat top and curved sides, identical to original.
• Precious‑metal versions: Cement‑grey dial with vacuum PVD plating (2‑4 μm) without covering sunburst patterns. Ordinary spray paint tends to be thick and fade easily.
IV. Hand Craftsmanship
• Material: Solid steel hands (not thin sheet metal), manufactured by Buff factory for solid feel.
• Finishing: Full mirror‑polished hands, free of burrs and scratches. Solid central axle, no hollow appearance.
• Shape: Hour / minute / chronograph hands match original length, thickness and curvature. Sharp second‑hand tip.
• Luminous: Even filling with neat edges, consistent with marker luminescence.
V. Scales & Luminous
• Bezel scales: Uniform engraving depth on ceramic bezel, full platinum filling and natural reflection.
• Dial scales: Crisp printing on sub‑dial scales, no blurring or misalignment.
• Luminous material: Swiss Super‑LumiNova, high brightness, long‑lasting blue‑green glow close to original.
• Filling process: Moderate luminous height on markers and hands with clean edges. V2 version features original‑style fine grain texture instead of smooth surface.
VI. Steel Bracelet (904L Stainless Steel)
• Material: Same 904L stainless steel as case, layered brushing and polishing.
• Links: Brushed sides and polished centre on each link for smooth transition. Even gaps and flexible articulation between links.
• End‑links: Seamless connection to case, no steps or looseness. Interchangeable with original parts.
• Feel: Weight and hand‑feel close to genuine bracelet, no cheap lightweight sensation.
VII. Clasp
• Steel version: Folding safety clasp, one‑piece formed without welding spots. Matte interior, polished exterior. Sharp and neat code, logo and dragon‑phoenix mark.
• New 4131 (rubber‑strap version): Extended clasp with approx. 3 cm quick‑slide adjustment. Tight memory steel spring for firm adjustment without slack.
• Fit: Smooth transition between clasp and strap, comfortable to wear and avoids digging into wrist.
VIII. Sapphire Crystal
• Material: High‑transparency sapphire with double‑sided anti‑reflective coating, ~92% light transmittance.
• Details: Laser‑etched tiny crown at 6‑o’clock (152 dots) with curved edge finishing. Crystal slightly protrudes above ceramic bezel at original height. No white gaps where crystal meets case.
